304 Stainless Steel Plate

What is 304 Stainless Steel Plate？

304 Stainless Steel plate is a type of stainless steel that is commonly used in various industrial applications due to its excellent corrosion resistance, high strength, and durability. It is typically made of 18% chromium and 8% nickel, which gives it its corrosion-resistant properties. 304 stainless steel plate is often used in the construction of equipment and machinery, as well as in the food and beverage industry, pharmaceutical industry, and automotive industry. It is also commonly used in architectural applications, such as in the construction of buildings and bridges.

304 stainless steel is a common material in stainless steel, density 7.93 g/cm³; can also be called 18/8 stainless steel, meaning that contains more than 18% chromium and more than 8% nickel; high temperature 800 ℃, with good processing performance, high toughness, widely used in industry and furniture decoration industry and food medical industry. But it should be noted that, food grade 304 stainless steel compared with ordinary 304 stainless steel, its content indicators are more stringent. For example: the international definition of 304 stainless steel is basically mainly containing chromium 18%-20% nickel 8%-10%, but food grade 304 stainless steel is containing chromium 18% and nickel 8%, allowing a certain range of fluctuations, and limit the content of various heavy metals. In other words, is 304 stainless steel is not necessarily food grade 304 stainless steel!
Common labeling methods on the market are 06Cr19Ni10, SUS304, of which 06Cr19Ni10 generally indicates that the national standard production,304 generally indicates that the ASTM standard production, SUS304 indicates that the Japanese standard production.
304 is a general-purpose stainless steel, which is widely used in the production of equipment and machine parts that require good overall performance (corrosion resistance and molding). In order to maintain the corrosion resistance inherent in stainless steel, the steel must contain more than 18% chromium, more than 8% nickel content. 304 stainless steel is a grade of stainless steel produced in accordance with the American ASTM standard.

304 stainless steel plate is the most widely used kind of chromium - nickel stainless steel, as a kind of widely used steel, has good corrosion resistance, heat resistance, low-temperature strength and mechanical properties; stamping, bending and other hot workability is good, no heat treatment hardening phenomenon (use temperature -196 ℃ ~ 800 ℃). Resistant to corrosion in the atmosphere, if it is an industrial atmosphere or heavily polluted area, it needs to be cleaned in time to avoid corrosion. Suitable for food processing, storage and transportation. Good processability and weldability. Plate heat exchanger, bellows, household goods (1,2 types of cutlery, cabinets, indoor plumbing, water heaters, boilers, bathtubs), automotive parts (windshield wipers, mufflers, moldings), medical appliances, building materials, chemical, food industry, agriculture, ship parts and so on. The content of which is strictly controlled 304 stainless steel, which can also be called food grade 304 stainless steel.
Most of the use requirements is to maintain the original appearance of the building for a long time. In determining the type of stainless steel to be selected, the main considerations are the required aesthetic standards, the location of the corrosive nature of the atmosphere and the cleaning system to be used. However, other applications are increasingly just looking for structural integrity or impermeability. Examples include roofs and side walls of industrial buildings. In these applications, the owner's construction costs may be more important than aesthetics, and it is OK for the surface not to be very clean. The use of 304 stainless steel works quite well in dry indoor environments. However, to maintain its appearance outdoors in rural and urban areas, it needs to be cleaned frequently. In heavily polluted industrial and coastal areas, the surface can get very dirty and even rusty.
However, to obtain the aesthetic effect in outdoor environment, nickel-containing stainless steel is required. Therefore,304 stainless steel is widely used for curtain walls, side walls, roofs and other architectural purposes, but in the seriously aggressive industrial or marine atmosphere,316 stainless steel is preferred. Stainless steel sliding doors, the superiority of using stainless steel in structural applications has been well recognized. Several design guidelines include 304 and 316 stainless steel. The "duplex" stainless steel 2205 has been included in European guidelines because it combines good atmospheric corrosion resistance with high tensile and elastic strength. Product Shapes Stainless steel is manufactured in virtually all standard metal shapes and sizes, and in many specialized shapes. The most commonly used products are made from sheet and strip, while special products are also produced from medium and thick plates, for example, hot rolled structural sections and extruded structural sections. There are also round, oval, square, rectangular and hexagonal welded or seamless steel pipes and other forms of products, including profiles, bars, wire and castings.
Process
The process of spray color art processing method of stainless steel products is: stainless steel products → silkscreen → etching → alkali treatment → silkscreen → oxidative coloring → alkali treatment → finished products.
The process of etching art processing method of stainless steel products is: stainless steel products → silkscreen → etching → alkali treatment → oxidation coloring → finished products.
The chemical coloring method of stainless steel does not use pigments and dyes, but immerses the stainless steel in a heated concentrated chromium sulfate solution for chemical coloring, which is characterized by good food resistance. The ink used in this processing method should have very strong acid resistance, and generally use UV vulcanized ink with special properties compatible with the treatment process.
